I think the pilot (Lakewood Plaza Turbo)'s artstyle would have been a better choice, as while it was pretty simplistic itself, it still felt like something unique and original. A sense of soul that isn't all that detectable in the final product for me.
As a result of the pilot's style being tossed out for the final product, this is why I personally think CN should aim to do better by, in the future, taking on people with more original ideas - as in not trying to make so many damn love letter references to anime most of the time (especially something they do that - again, I find rather annoying in SU, for example...), while also at the same time, not relying on cheap art-style decisions, especially.
